We sell software to manage risk and compliance processes in big financial institutions. Lots of data, complex workflows, different natural and computer languages, you name it.

At the moment we're looking for a generalist role and two specialist roles:

2. DEVOPS: We're increasingly getting asked to manage complex data privacy problems as well as being probed on security. If you know what an HSM is, or have managed sensitive data in a devops context, we'd love to talk to you.

3. GRAPH DATA: Most risk problems boil down to relationships that can be teased out of data. We're looking for someone who has worked on complex graph data issues. Experience at scale is a big advantage. If you have strong opinions about Spark, Neo4j and/or Palantir, get in touch.

We're building a flexible and all-encompassing approach to security.

If you've ever worked at a business which sells to other businesses (or if you've been a contractor yourself) you'll appreciate the pain that comes with getting your customers to pay promptly. We solve that pain, as soon as a company has issued their customer an invoice we can advance them the money (the companies then pay us back when their own customer pays them) so they have it instantly so they can pay their own suppliers and staff on time.

We want to press the accelerator pedal on our growth but we know we need to make smart decisions in order to enable that. Whether that's picking the right KPIs for product decisions, segmenting our customer base or modelling the credit limit we can extend to a user.

We need a Python Engineer to join our growing team and contribute significantly to the software and system design of our services. You will participate in an agile product team of engineers, building and operating our systems. You will build, scale, and operate a multi-tiered system separated by APIs, following best practices.

StreetTeam believes in freedom and ownership with the focus entirely on the value you create – there are no set hours, meetings are optional and you can take as much holiday as you need. We only care about the results you deliver. We are free-thinking, fast learners who want to inspire change. Are you?

I'm looking for a brilliant Java engineer with AWS experience to take on a very senior technical role in my team. We're a super versatile, cross-functional group of engineers who work on our integrations with third parties.

Capital One is a pretty awesome place to work; nice balance of "grown up" company and fun startup. Good canteen, fun spaces, relaxed work environment. Salary and benefits are excellent.

As a senior/lead engineer at our Nottingham office you will work within an agile feature team on a wide array of intriguing problems; such as API authentication, on-boarding external developers and auto-scaling infrastructure. Our teams have a high degree of empowerment to own their products from design to production. We are just beginning a journey into the cloud and want you to help take us there.

This isn't a line management role; we call you an "individual contributor" who is at the top of their game and has a passion to focus on engineering over management. At Capital One we cherish engineers like you and have excellent career development opportunities that don't require you to take on a team.

Interview Process; we've worked on this for a while and it's slick. Simple online coding challenge, phone-screen, 1-day interview & we commit to being able to make a decision without getting you back for second-rounds

Circles was founded in 2016 with the belief that when it comes to supporting each other, social networks are the wrong model. Our idea is that an inner circle of trusted people, empowered with tools that enable them to be more effective and connected to the individual’s needs is the best model for long term care. Our first focus is on issues related to mental health.

- A senior backend engineer to work on our (currently) Rails driven API system, along with the associated operations.

- A senior mobile engineer to work on our React Native front-ends, which also have native code components

- Less senior mobile engineers to work on the React Native/native code front end systems.

As we're small, everyone will probably do a bit of everything, including helping to build our "prompting engine": a real time, privacy centric data analytics platform to give insights to your trusted circle members about your state.

We're a new company, funded, and pretty tech agnostic. We don't believe in below market salaries for startups, so you'll be paid at market rate and still have options for equity. We're also trying to create an environment in line with our product direction: a supportive group of peers trying to do good work without damaging ourselves or others. We do remote and on-site work, but can't really support a totally remote employee, so you'll need to be available in London a few times a week. Alas, we also can't sponsor visas.

If anyone would like more information than the job specs provide, please just ping me directly on adam@circles.care.

HUGHUB is a cutting-edge digital insurance platform. It allows brokers and insurers to offer their clients a simple, convenient place to purchase and manage all of their insurance products.

The platform is unique in the market and promises to become a disruptive force in the insurance industry here in the UK and as the product gains traction, it will be adapted and ported to the North American and Asia Pacific Markets so it has enormous growth potential.

Our developers utilize all the latest technologies and the platform contains a number of highly innovative technical features that differentiates it from anything in existence and the road map of feature/functions will continue to build on its uniqueness. The product has a front-end written entirely in Java/TypeScript, Angular, Node.js and a back end utilizing RESTful web services (.NET WebAPI), CQRS and MongoDB.

The ethos of our development team is that of high performing entrepreneurs with superior technology talent. The delivery style is that of a “consultant developer” working closely with the end client to deliver in a truly DAD style.

The company is young, energetic and driven and we work closely together at our office in Mayfair. We are looking for a new team member to join us who has experience with the following technologies-

Required Skills: • Full-stack development • 5+ years’ developing .NET products • REST Web services • Knowledge of architectural design patterns • Angular.js, or a similar JS MVC Framework • Good understanding of the workings of the Task Parallel Library and its merits • A good understanding of SOLID

It is a close knit team currently comprised of 3 developers and we are expecting to grow rapidly over the next year as we take more clients on board and expand the product's functionality so it is an exciting time to join.

We're one of the biggest travel metasearch products in the world by traffic... and we want to 10x that, again :)

Hiring at an experienced level in lots of key disciplines: backend with microservices & distributed systems, big data & data science, full stack (modern frontend + api skills - particularly Node or Python), designers, product, iOS & Android. We are growing in all of our European offices - London and Barcelona being the two newest. In short, if you've got good industry experience, know what best practices look like, and have the drive to make things better, we're interested.

We want to hire people interested in large-scale challenges and building new products. We have an incredible amount of historical data and a unique position in the market. What should the future look like? How do we best use our data, our scale and new technologies to our advantage as we grow? We're particularly interested in data-driven personalization and recommendation, exploring new travel products and experiences, as well as developer enablement and tooling.

We're one of the very few unicorn companies HQ'd in Europe who are profitable, and have been so for the past 7 years. Our CTO Bryan Dove joined us from leading Amazon S3 - in London you would be working closely with him alongside some very experienced industry figures in a cool and central location.

Please ping me an email at alex (.) treppass [at] skyscanner.net for a referral. Happy to answer questions or pass you to someone who can. CV in Word / .doc format would be ideal, pdf is fine.

On a personal note, I see a lot of freedom, responsibility, accountability. Engineers have a lot of room to make decisions and move fast, and the encouragement to make us better. It's exciting.

Looking to join a small 4 person, casual, team of PhD's/Unix hackers who pride themselves on quality? Looking for a well funded startup run by an experienced dev team who have been working together for 10 years? Do you love python, postgres, pyramid and sqlalchemy?

Drop us a line - we're working on a large, well funded, project where we process (for search & convenient reading) thousands of documents a day for the finance industry and need a solid pair of hands with a sense of humor and a life outside of work. This involves a pile of aws infrastructure, and a fair amount of tricky reporting and data-collection work, as well as things like 'similar to this document' and surrounding compliance. Lots of good concurrency issues and careful balancing of resources & profiling profiling profiling... and testing!

As pretty much everything we do is based on open source libraries we try to contribute back where we can, have contributed small patches to sqlalchemy & deform.

We will happily consider a range of experiences, but would prefer someone who is familiar with our tool-chain, any experience with elastic search & recommendation mechanisms a plus. Some frontend js/css knowlege, and sysadmin (ansible, linux) knowledge welcome too although we are happy to share internally.

Our main dev office is in Canterbury, Kent, but we are looking to grow the team in our London office near Baker st.

On the Data Sci side, we are looking for someone to start our data science practice. This role will entail a lot of freedom as we expect the hire to help build up the analysis/recommendation stack. It is expected that you will also need to figure out if there are an missing data that we need to collect, design the model we will use, choose the software (we have experimented with Spacy.io but are open to suggestion). We also have a strong academic contact we can lean on for machine learning expertise.

Drop us an email to contact at our domain name with a CV, and any work you may have open sourced online.

Our interview process will usually involve a skype chat, followed by a group chat with the whole team. Depending on background we may ask you to complete a task or two.
